7x10^3

answer in standard form
10^

Given:

The expression is:

To find:

The simplified form of the given expression in standard form.

Solution:

We have,

It can be written as:

Therefore, the required value is .

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
